Increased Myocardial Infarction Risk Following Herpes Zoster Infection. | LitMetric

Increased Myocardial Infarction Risk Following Herpes Zoster Infection.

Open Forum Infect Dis

Department of Pharmacy, Veterans Affairs Western New York Healthcare System, Buffalo, New York, USA.

Published: April 2023

Background: Myocardial infarction (MI) has been reported as a postinfection sequela of herpes zoster, but with limited data on incidence after zoster and protective effect of the zoster vaccine. This study investigates the risk of developing an MI 30 days postzoster, determines patient-specific risk factors, and investigates the impact of herpes zoster vaccination.

Methods: This retrospective cohort study included patients who received care at a Veterans Affairs facility between 2015 and 2020. Time to MI was determined from either 30 days post-zoster infection (zoster cohort) or a primary care appointment (control cohort).

Results: This study assessed a total of 2 165 584 patients. MI within 30 days occurred in 0.34% (n = 244) of the zoster cohort and 0.28% (n = 5782) of the control cohort ( = .0016). Patients with a documented herpes zoster infection during the study period were 1.35 times more likely to develop an MI within the first 30 days postinfection compared to the control cohort. Patients who received the recombinant zoster vaccine were less likely to have an MI postinfection (odds ratio, 0.82 [95% confidence interval, .74-.92]; = .0003).

Conclusions: Herpes zoster infection was associated with an increased risk of MI within the first 30 days postinfection. History of prior MI, male sex, age ≥50 years, history of heart failure, peripheral vascular disease, human immunodeficiency virus, prior cerebrovascular accident, and renal disease increased odds of MI 30 days postinfection with herpes zoster. Herpes zoster vaccination decreased the odds of developing an MI in patients aged ≥50 years.
